Ubuntu :: External Hard Drive Now Stuck In Read-only Mode?
Jan 22, 2011
so here's my issue and what I think is causing it right now. I have a 1TB external usb hard drive that has worked perfectly, but recently I set it up a mount point for it in fstab so that I could create a SMB share on the drive so I could stream videos and pictures to my TV through my Wii using WiiMC. This now works perfectly, but now the hard drive has been set into read-only mode. When I use sudo to try to chmod the drive or the folders on it, it does nothing. When I right-click on the drive and check the permissions tab, it says the owner is root and all the options are greyed out.
I've read through several posts on similar topics to this, but none of them have been very helpful as they suggest using command line tools that I don't know how to use, so I'm hoping someone here can give me concise, step by step instructions of what to type in, or what settings to change in fstab to solve my little problem so I can start copying stuff back onto my drive. I'm running Ubuntu 10.10 and the filesystem on the external drive is FAT32. Here's some more info you might need:
I recently bought 320 GB Trancend external hard disk and working fine days back.Earlier i could copy from and to the hard disk with out any issue. I dont know what happened after that now i am not able to write any files in to the external hard disk. This is not NTFS formatted device. here is some of the out put from terminal.
Code: sundar@sundar-sundar:~$ fdisk -l Disk /dev/sda: 120.0 GB, 120034123776 bytes
I have a computer with Ubuntu 10.04, with few disk space. For downloading some torrents, I've connected a USB hardrive, ext4 formated. But this idea wasn't a solution, because the drive keeps getting read-only permission... Is there any way of prevent this to happen?
I was in the process of backing up data from my hard drive to an external usb drive when the drive suddenly became read only. Does anyone know how I can make it read/write again? I am using Debian Lenny and the drive is ntfs formatted. I have another ntfs formatted usb drive that is not effected in this way.
I am using Thunar and XFCE4. I started with the minimal install CD, so this is not exactly Xubuntu as I do not have Xubuntu-desktop package installed. I installed psydm to be able to easily edit and control mounting, fstab etc... Anyways, I can't figure out how to write to this disk. I have amended the Thunar icon to read "gksudo Thunar" as its command. It opens Thunar with whatever elevated rights that would come along with the command. I still can't write to the disk. If I change the permissions for the disk under the properties tab to be "read&write" for the user group, It asks me about something to be done retroactively to files. No matter whether I choose yes or no here, it still does not change the disk to a writable disk.
No love and no ideas. Can you help me write to this disk ? I run as a user called "user" so maybe I should not have made Thunar open as "gksudo" ?
I administer a remote server via SSH that runs CentOS 5.5. I have been unsuccessful in all my attempts to write to two different external USB hard drives with a single ext3 partition when logged in as root.
When attempting to create a "test" directory I get one of two messages:
Both drives *appear* to have filesystem issues. When I run an fsck on either drive, I get:
Keep in mind this is a newly-formatted, empty drive.
Not putting stock in the odds that I've had two hard drives (different sizes and brands) with the exact same hardware problem, I'm going to assume this is a software issue, although maybe it isn't. Hence, my post in "Linux - General". I've heard talk elsewhere of controller (chipset) issues coming into play. Is this valid?
Okay, here's the information you'll need to make a diagnosis....
Here's the output of a "df -h" command:
Here's the contents of my /etc/fstab:
Here's the output of "cat /etc/mtab":
Here's the output of a mount command:
Here's the output of fdisk on the device in question:
The number of cylinders for this disk is set to 48641.
There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help):
I've got someone with access to the box if necessary. But it might take days to implement solutions since this isn't his full-time job. Remote solutions are, therefore, preferable.
i borrowed an external hard drive from my friend to back up a load of stuff on my windows partition before reinstalling it. I am doing this through ubuntu. I am trying to zip up folders like My Documents etc and chuck them on the external hard drive but it always comes up with errors to do with read/write permissions. In the permissions tab on the folder properties of the ext hard drive it says I am owner but i have no file access (only folder access is create and delete files). When i try to give myself read/write permission it just goes straight back to nothing when i look at it again.
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
I have a laptop with only 30GB storage and I want to install Lubuntu in virtual box but Lubuntu needs 5GB of storage space which i dont have. Could i use an external 160GB hard drive to act as the hard drive for the virtual machine without affecting the files that are already on the external hard drive
I realized after spending some time performance tuning my mini Linux server that the hard drive is stuck in IDE mode, and I can't get the controller to be discovered in AHCI mode.EDIT: I should add that I'm running Vector Linux 6.0 Lite, which is based on Slackware 13.0. The Kernel version is 18.104.22.168.
The mobo in question is actually a small mini-ITX board from Foxconn. Here is a links to the specs:url.I use it for a media server, and so far the drive I'm using (Hitachi HDE721010SLA330) is working fine in IDE mode (apparently).
I have a strong suspicion that the crappy Foxconn BIOS supplied with the board is not initializing the Intel 945GC controller in AHCI mode. There is a BIOS entry for setting the controller to "Advanced", but I don't think it's doing the job.
I use to be able to mount a usb and stick and copy over files to it. Now when I plug it in it mounts as read only and I cannot change it. I did not change anything on the system. I have su access and really nothing is new on this laptop. Any thoughts one what i can look at? I need to write data to usb all the time. I rebooted too. same issues.
I would like to install Linux Ubuntu 11.04 on an external hard drive - its partitioned and ready for Linux.I've downloaded and burnt the .iso file to a DVD so its all good so far...First of all... is this possible without messing up my macbook? I don't particularly want to break into my macbook to disconnect the hard drive (I read on a tutorial for a previous version of Ubuntu that I'd have to do that... - does it still apply to 11.04?) - as it voids the warranty (I checked ).The reason I ask this is because I had a friend who partitioned their internal hard drive and installed Ubuntu on it. But after installation was complete they couldn't boot up Windows 7 or Ubuntu... and it resulted in them having to clean install Windows 7... - I don't want to end up in that situation
Second... If it is possible to install it without messing up my macbook... - Do I just follow the install instructions but just make sure that where possible I make sure that everything is installed on my external hard drive?...I really need someone to put my mind at rest that everything will run smoothly and that I'll be able to run Mac OS X as usual but also that I'll be able to boot from my external hard drive to run Ubuntu.
I have 350GB external Western Digital USB hard Drive.When I try to remove it from the system by executing Safely Remove Drive menu the fedora 15 system gets stuck.The processor starts giving a hum sound and it goes on even if it is left for half an hour in the stuck state.The Mouse is not working and everything is halted.
Been happily going along with Lucid Lynx, locked in, no problems. Slowly sorting through many files on an external 500 GB USB drive, moving into useful sub-folders. Today, I cannot write to any folders on that drive -- read only. ?!?! I run nautilus as root, still no joy. (Using nautilus GUI to browse files to move to other folders.. how can I change these settings to allow me to be able to write to this drive again?
i have installed fedora 14 with so many libraries ,development tools installed on my pc but i usually have to present some projects which can run on my system .........and can't be executed or compiled due to absence of libraries and tools there so, i there some way to so that i can use this current installation on my hard drive of my pc to some external media like external hard disk and plug and use that installation anywhere on any system..
I downloaded x86-64 hybrid DVD and done everything according to instructions from Installation without CD - openSUSE.After booting from USB HDD, the first page took about 3 minutes to switch menu to the installation media option then afterwards the installation got stuck on Hard drive detection (probably 2 hours before i rebooted into windows 7). Installation scenario is:
Machine: Compaq presario C767TU HDD: 320 GB with Windows 7 Ultimate on root partition, all other partitions NTFS Free Space for Linux: 30 GB (Extended partition) currently having Mandriva 2010 with /swap 2GB, / 10GB,
Short version: How do I reformat an external hard-drive (read-only, NFTS) so that I can rw to it.
Long version: I had a self-built Ubuntu desktop that is now dead. I have pulled out the hard-drives and have bought one of the connector's to convert the SATA cable to USB so I can put the data on my Mac. Unfortunately, my Mac is not able to read the hard-drive for some reason... So, I've decided to boot my old Ubuntu laptop to pull the files from the SATA drive to an external drive then hopefully connect that external drive to transfer the files to the Mac. The external drive is currently formatted as NFTS and I'm unable to reformat it with gparted--I'm guessing that's because it's read-only mode...?

I set up a server using ubuntu 9.10, with two hard drives in a hardware Raid 1 setup and with two more drives for recurring backups. The problem is that the two drives for backup are set to read only and won't allow me to change the permissions even when logged in as root. I have tried putting "rw" into the "fstab" file with no luck, I have also tried running "gksudo nautilus" and "fsck -r /dev/sdc" but still have the same message that I don't have the necessary permissions to complete the task.
**I just tried erasing the data on the disk and creating a new partition, the disk utility allowed me to erase the data and create FAT32 partitions with the same permission problems but would not allow an EXT partition or NTFS partition (it would give and error message stating:"Error creating file system: helper exited with exit code 1: helper failed with:mke2fs 1.41.9 (22-Aug-2009)")**
***I fixed the problem by fixing a formating problem in fstab and reformatting the drives to ext4.(the fstab had a problem with the way that I broke up the lines when I input the info for the new drives, and I didn't realize it until I maximized the window in gedit.)***
I have a simple WD external USB hard drive, but when I plug it into my computer nothing happens. Not only is there nothing popping up, but I cannot access it through the file browser. The light on the hard drive turns on as usual.
I was busy making backups to my external hard drive just now, but Ubuntu crashed 10 mins into the backups. After rebooting the affected folders are now Read only, and I cannot add or remove anything. This is extremely annoying, I already threw away two USB flash disks because the same thing happened to me in the past. I don't want to throw away the external because it's far more expensive and packed with backups.
Symptoms: I can write or delete a file to the hard drive, in any folder, accept the folders that was being accessed when the computer crashed. I have tried to change permissions, but I get an error. I tried opening a terminal and sudo rm -r that folder, but I get a input/output error. I'm running Karmic. Backups were made by Back-in-time.
Below is results from attempt at formatting my hard drive. As you can see a driver is installed, but not working. Perhaps something is missing? Seems a bit odd that a "unable to read" comes back when disk data is reported. The drive just went through a low level format. BTW this is a fiber channel drive. Also on board are 5 scsi drives. Adaptec raid card. Not sure if that would have any relevance, but there you are.
So I recently got a WD MyPassport external hdd with 500gb capacity. I formatted it to NTFS so that it would be more efficient transferring data between my Ubuntu and Win7 dual boot. But now I want know if it is possible for me to create a 100gb FAT32 partition on the external without destroying the data on it.
My Toshiba 500Gb USB hard drive is not being detected anymore when i insert it in 9.10. It only started doing this from last week, it was fine before (and it works fine in Windows XP). The connections are fine and all, because when i type "lsusb", i see it as follows:
Bus 001 Device 003: ID 19d2:0063 ONDA Communication S.p.A. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 004: ID 0930:0b09 Toshiba Corp.
Is it possible to use Ubuntu for a malfunctioned external hard drive?A year ago my external hard drive malfunctioned and I cant get into it, though it plugs in alright and the computer recognizes it, I'm hoping that maybe precious files havent been wiped and are just stuck in there.Is there anyway that Ubuntu can help?Also, if there is, what exactly is the first thing I do or type into the terminal?
I'm trying to get ubuntu 9.04 to recognize a Maxtor One Touch III USB external hard drive. This drive has been formatted and used on a Windows XP. I cleared everything off but am trying to see if I can arrange it so that I can back up from linux and access (if need be) from a Windows machine.
Here is what I get with fdisk -l:
/dev/sda1 * 1 14219 114214086 83 Linux /dev/sda2 14220 14593 3004155 5 Extended /dev/sda5 14220 14593 3004123+ 82 Linux swap / Solaris
I am having problems mounting an iso on my external hard drive. I do not want to move it onto my linux partition because it is 3.6 GB. I have a directory made (/media/iso) that I would like to mount it in, but if that doesn't work then I don't care where it goes. After I mount it I want to be able to run it using Wine, but that will come later. For now I just need to get it mounted. And, of course, I am fairly new to linux/ubuntu.
